Using the Trans (Forma) app visitors to the exhibition could interact with the models that Lukasova and Rees developed for the exhibition. Activated by the photo targets the models moved into the scene to form random combinations that viewers could examine by navigating the app. Screen photos of the combinations could be taken and saved to the app to be shared via email. The targets where taken from in and around the setting for the show: the jesuit monastery, the sites of Kutna Hora and other sites.
